Raptor Fractions

“The number of breeding pairs of hen harriers in England so far this year ranges between 0 and 1.” (https://raptorpersecutionscotland.wordpress.com/2016/06/06/how-many-hen-harriers-breeding-in-england-this-year/)

0.5 of a breeding pair? Just out of interest, is it hermaphrodite?

“The probability of 5 or more male Hen Harriers disappearing through ‘normal’ levels of mortality over a breeding period from 9 nests is 0.0033% … So there must be something pretty odd happening.” (http://markavery.info/2015/09/22/wondering2/)

Yes, that’s a 1 in over 30,000 chance. Pretty unlikely. Well done the grouse shooting industry for allowing us to experience such a rare event.

“Two more red kites have been confirmed by Scottish Government testing to have been illegally killed in north Scotland. … It is doubtful whether either of the corpses of these birds would have been found if the satellite tags had not been in place.” (http://www.rspb.org.uk/media/releases/406182-two-more-red-kites-found-illegally-killed-in-north-scotland)

If only there was a way to track where the birds were before their deaths.


“We hope that the reduction in reported illegal poisoning of birds of prey in 2012 will be maintained, and that we see a clear effect on the ground with birds of prey returning to our skies.” (http://www.rspb.org.uk/media/releases/354275-rspb-scotland-welcomes-government-report-into-wildlife-crime-in-scotland)

The effect on the ground is expected to be a bird-shaped shadow.
